Specification of Letters Patent.

Patented Au 10, 1915.

To all whom it may concern:

Be it known'that I, HowARD D. COLMAN, a citizen of the United States, residing at B-ockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Textile-Machines, of which the following is a specification.

This invention relates to apparatus for operating upon warps, as, for example, for

Another object of the invention is to provide power means for driving the mechanism of a textile machine which is movable into and out ofoperative relation. to the apparatus that supports the various pieces of work, and in which the mechanism is arranged to travel upon the bed of the machine.

The invention also relates to other features hereinafter described.

In the accompanying.drawings, Figure 1 is a front elevation, somewhat shortened by breaking out portions, of an apparatus embodying the features of my invention. Fig. 2 is an end elevation of said apparatus. Fig. 3 is a sectional view taken in the plane of dotted tion on line 4 at of Fig. 1. Fig. 5 is a fragmental top plan view of the apparatus. Fig. 6 is a section on line 6 6 of Fig. 1. Fig. 7 is a section on line 7 7 of Fig. 1. Fig. 8 is a front elevation of the lower part of the means for suspending a removable element of the warp-tying machine. Fig. 9 is a section on line 9 9 of Fig. 8. Fig. 10 is afragmental detail illustrating a difierent position of the parts shown in Fig. 9.

I will illustrate and describe my invention as embodied in warp-tying apparatus, without thereby intending to limit the invention to the tying of warps, since it is obvious that the principle of the invention is applicable to warp-drawing machines.

The embodiment herein illustrated by way line 3 3 of Fig. 1. Fig. 4 is a sec-- of example comprises a group or set of supports or frames 1 each adapted to support a pair of warps, and a warp-tying machine movable past said group of frames. The warp supports or frames may be generally similar to that illustrated in Patent No. 955,383, issued to me on April 19, 1910. Each of said supports, in the present instance, comprises two posts 2 for supporting a 100m beam a having thereon a new warp, and arms 8 for supportingloom harnesses operatively associated with a section of warp cut from a loom. Said sectionof warp will be hereinafter termed an old warp.

Q The warp-tyingmachine t may be generally similar to the one illustrated and described in British Patent No. 10384 of 1905. The present form of said machine is mounted upon rollers 5 6 so that it may be traversed past the group or row of warp-supporting frames. If desired, some suitable means may be used to hold themachine in adjusted position, as a brake et If desired, the warp-tying machine may be arranged to travel upon rails 7 8 laid upon the floor in front of the warp-supporting means. As herein shown, the rail 8 is grooved and the rear rollers 6 have flanges thereon to travel in the groove of the rail. Upon the bed 9 of the warp-tying machine is a carriage 10 supporting a. suitable mechanism for selecting threads from an old and a new warp' and for uniting such selected threads. This mechanism may be of any suitable character, as, for example, thatfully illustrated and described in the before-mentioned British patent. The driving connection between the carriage 10 and the bed or framework of the warp-tying machine may likewise be of any suitable nature, as, for instance, that disclosed in my said British patent.

The whole or a suitable portion of the new warp to be operated upon is supported upon the bed of the machine in any suitable manner, as, for instance, that illustrated in the said British patent, while the whole or a suitable portion of the old warp is supported in a warp carriage 11, which may be similar to the one shown in. the British patent before referred to.

For convenience .in positioning the new warp in the warp-tying machine, the warp carriage 11 from its normal or operative position. I

have herein shown means for supporting the carriage so that it may be readily moved aside. I have also provided means for traversing the carriage 10 upon the bed 9 and for actuating the mechanism on said carriage.

The warp-carriage-supporting means and the drive for the warp-tying machine are mounted upon a framework which may be constructed as follows: Bars 12 and 13, which may be angle irons, fixed to and rising from each side of each warp-supporting means 1, are joined at their upper ends by horizontally extending ward ends of the bars 14 are secured to a bar 15 extending in front of and above the group of warp-supporting frames and running to a point at some distance beyond one side of such group. If desired, a diagonal brace 16 may be arranged between the bar 15 and the rear portion of one of the bars 14.

' To the extended end of the bar 15 are fixed r a suitable means,

two brackets 17 and 18 spaced a suitable distance apart along said bar. In the outer portions of said brackets is mounted a track 19 which, if desired, may be tubular, as shown in Fig. 6. As illustrated in said figure there is a slot in the lower side of the tube constituting the track, the surfaces at opposite sides of the slot forming rails upon which rollers may run, as will appear hereinafter. The extended end of the bar 15 is supported, in this instance, by a tubular post 20 attached at its lower end to the floor in any suitable manner. A track 21 which may, if desired, be similar to the track 19 is supported from the bar 15 by suitable means such as the bracket 18 and a sufficient number of brackets 22 23 24 25 26. The track 21 extends in front of and above the group of warp-supporting frames and to a point at a suitable distance from one side of said group, as indicated in Fig. 1.

In the present embodiment, power is communicated to the warp-tying machine by means comprising a short shaft 27 carried by the bracket 26, said shaft having fixed upon one of its ends a grooved pulley. 28 which receives a drive belt 29 extending over a countershaft or other suitable source of power. On the opposite end of the shaft 27 is fixed a grooved pulley 30, and each of the brackets 23 and 25 has mounted thereon a grooved idler pulley 31. The track 19 provides means for supporting one element of a suitable slack take-up for a belt 32 running over the pulleys 30 and 31 and suitable pulleys on the warp-tying machine. In this instance the slack take-up comprises a carrier 33 provided with rollers 34 which run Within the track 19. On said carrier is a grooved pulley 35 for the belt 32. The carrier 33 is arranged to be moved along the track 19 in the direction to take up slack by such as a weight 36 atbars 14. The fortached to the carrier through the medium of a suitable flexible connection 37 extending over a guide sheave 38 near the upper end of the tubular post 20.

Fixed to the warp-tying machine is suitable means for guiding the driving belt 32 to the driven parts upon the machine. In this instance, said guide means comprises a bracket 39 fixed to the warp-tying machine, suitably braced and of such height as to sup port guide pulleys 40 at a suitable height above the floor so that the driving belt 32 may be out of the way of the operator. Upon a stationary part of the warp-tying machine are guide pulleys 41 for guiding the belt 32 into operative relation with a pulley 42 upon thecarriage 10. The shaft of the pulley 42 may be provided with a crank 43 for manually driving the mechanism and feeding the carriage.

The pulley 42 is preferably connected to its shaft by a suitable clutch arranged to be operated to disconnect the pulley from the shaft when the work in the machine has been completed or in case the thread-selecting mechanism stumbles.

One suitable form of such automatic throw-out is fully illustrated and described in my said British Patent N 0. 10,484 of 1905. The means for supporting the warp carriage 11 for convenient withdrawal consists, in this instance, of a carrier 44 provided with rollers arranged to travel within the track 21, said carrier having fixed thereto two vertical downwardly-extending rods 45. A cross-bar 46 is fixed to these rods. The lower ends of the rods are tubular to receive rods 47 fixed to brackets 48, a crossbar 49 extending between said brackets.

To the lower side of each bracket 48 are fixed two straps or loops adapted to support rods 11" forming part of the warp carriage 11. The devices 48 49 50 constitute a means for connecting the warp carriage to the rods 45. Said connecting means is vertically movable with relation to the rods 45, and is arranged to be moved by means here in shown as comprising a rock shaft 51 having crank arms 52 thereon, said crank arms being connected with the cross-bar 49 through the medium of links 53. The upper portions of said links are bent so that the point of pivotal connection between the links and the crank arms may be thrown over center to hold the warp carriage 11 in ele vated position. The shaft 51 may be rocked by means of the hand lever 54 fixed upon one end thereof. 55 is a tension spring extending between the rock shaft 51 and the cross-bar 49. lVhen the hand lever 54 is rocked to lower the warp carriage 11 and is thrown against the stop 56, the point of pivotal connection between the links 53 and the crank arms 52 is slightly over center, and the spring 55 holds the links and crank arms in such relation, thereby locking the carriage-connecting means in its lowered position. Then so lowered, the straps 50 are out of contact with the rods 11 In use, a new warp and an old warp are placed in one of the warp-supporting frames 1, and the whole or a portion of the width of said warps is operatively placed in the warp-tying machine, said machine being positioned properly in front of said warp-supporting frame. The operator now pushes the carriage 10 forward until the mechanism on said carriage is in proper relation to the threads of the two warps. The operator then clutches the pulley 42 to its shaft to permit the belt 32 to drive the warp-tying mechanism and feed the carriage 10. ile the machine is operating upon the two warps as just described, the operator places another pair of warps on the adjacent frame 1 and prepares said warps for reception in the warp -tying machine. When the warp threads contained in the warp-tying machine have been united, the mechanism is automatically stopped, as described in said British Patent No. 10,484 of 1905. The operator thereupon removes the united warps from the machine and returns the carriage 10 to its initial position upon the bed of the machine. The operator then moves the warp-tying machine along the front of the group of warp-supporting frames into position to operate upon another pair of warps or section of a pair of warps, and places the warp-tying mechanism in operation, as before. When the carriage 10 advances upon the bed 9 the take-up 33 furnishes the necessary slack to the belt 32. When the warp-tying machine is advanced along the front of the row of warp-supporting frames the belt automatically adjusts itself by running over the guide pulleys 40 41. When the warps upon one of the frames 1 have been united and the machine has commenced to operate upon the warps in another frame 1, the united warps are removed from the first mentioned frame and a new set of warps placed therein and prepared for reception by the warp-tying machine.

It will be seen that the provision of a plurality of warp-supporting means permits the operator to prepare one piece of work for the machine while the latter is operating upon another piece of work, thus P rmitting of a substantially continuous use of the machine.

l Vhen a new warp is to be placed in position in the warp-tying machine, the warp carriage 11 is elevated by rocking the shaft 51 into the position shown in Fig. 9, the carrier 44-, with the warp carriage 11 suspended therefrom, being then pushed along the track 21 to a point at one side of the Warp-tying machine.

I would have it understood that the invention is not limited to the construction herein shown and described, for various modifications will occur to those skilled in the art.
